FIELD AND LABORATORY WORK - Continued 1 �Typical undisturb"d samples were selected for expansion test to determine expansive soil 1 . potential at existing site conditions. A bulk sample was tested for maximum density to determine percent relative compaction of existing subgrade soils. A specimen was cut 1 from the bulk sample and subjected to expansion tests to determine the expansive soil � i 1 potential of site soils compacted to 90 percent relative compaction at moisture contents j wet of optimum. r � 1 Maximum Density and expansion test results are presented on the attached Plate C-1 and f 1 C-2and Percent Relative Compaction is posted to referenced boring logs. i i 1 SITE CONDITIONS { 1 The walks under evaluation consisted of large concrete rectangles placed in an offset pattern. F 1 � t `Valk slab sections bordering the north side of the structure have settled differntially, with 1 l ' edges of sections north of the covered walk canopy columns generally lower than edges f yi 1 south of the canopy columns. Walk slab surfaces along the cast side of the structure were }i � undulating with respect to one another, particularly in areas of olive tree planters. rdges ' 1 of slabs %:•ere noted to be generally 2 inches !ower than the top of curb fronting Camino t 1 Capistrano. f Walk slab sections along the south building line, between the south side of the building and 1 . the p!anier area 10 the so"!), \Vere generally level witl) generally uniform alignment 1 between cages. The walk bardering the west side of the structure was generally uniform and in good 1 g condition. 0 2359 1 ��\ Parc 2 77117W 7 WE CONDITIONS - Continued What visually appeared as a replacement patch was noted at the southeast corner of the site where Del Obispo intersects Ca:nino Capistrano. EVALUATION Based on information obtained during field exploration and review of available laboratory I ' lest data the following evaluation is presented. ' FIELD EXPLORATION 1. Concrete S!abs: Thickness of concrete slabs was 2.5 inches at 3 of 4. .test hole locations. A thickness pf 3 inches was measured at the location of Test Hole: No. 3. No reinforcing was 1 noted during slab penetration, and the concrete was easily penetrated with a steel core bit attachment- to the auger drilling rig. Lack of reinforcing could permit ' excessive movement between slab joints. r 2. Base Material: ' Sand grid graven base thickness underlaying slabs varied from 4.5 to 9 inches at test Poring locaticns. -Thfs base material a!so appeared loose and dry when penetrated. ' If.placcia in-such a loose condition, the overlaying slab sections would have settle differentially. , 3. Planter Areas: .No shallow major tree root structure was encountered in borings drilled near planters in the cast sidexva!k area. This would tend to indicate that tree roots are ' not a major contributing, factor to slab undulations in this arca. ti 2359 Pane 3 r - OW) ELPLORATION - Continued.• rLABORATORY TESTS r1. Percent Relative Compaction: When compared to the maximum density test, field densities indicate surface soils at j r percentages of compaction varyng from 77 to 35 percent. This would tend to ' indicate that little or no compactive effort was applied to the site subgrade soils iprior to placing Ilse overlaying base material. 2. Expansive Soil Characteristics: r rExpansion tests conducted on slices removed from undisturbed core samples indicate f low to moderate swell potential remaining in existing site soils. This indicates that rvarying degrees of expansive sbll potential probably existed at the time of i construction and that movement would be non-uniform with the addition or ! r subtraction of moisture contents. this condition coved be a contributing factor for non-uniform walk surface conditions in the area of planters. Expansion test conducted on a combined sample of subgrade soil types encountered indicate site soils are potentially highly expansive when recompacted 50 percent of ' maximum density at presaturation (4 percent over optirnurn) moisture contents. ' If recompacted to moisture cements at or less than optimum, borderline critical expansive soil potential is estimated for site soils. SUMMARY r It is our opinion that the followin3y Ib2mS Were contributing faCt O.'S 10 Uneven Walk rConditions. I.- Loose Material o`. non-uniform thickness. 2. Nan-uniform density and low percentage of relative compaction for sub;r'adc soils 0 the sick-walk structu;a! section. 2359 Pane 4 SUMMARY - Continued • 3. Lack of reinforcing, or lack of sufficient design for walk slabs to resist differential movements in underlaying supporting materials. ' RECOMMENDATIONS ' It is not considered feasible to correct the uneven walk surface conditions by utilizing slab overlay procedures. Use of grout injection procedures to underlaying sand is not considered a suitable alternate, in that, such procedures would not add appreciable ' structural characteristics to the overlaying slab which is necessary to conteract potential total and differential movements from expansive soil pressures. It is our opinion it would be necessary to remove the existing walk, improve the underlaying soils and base material, and provide a new walk structurally designed to resist { expansive soil pressures. Provided in the fo!lowir,i are recommendations for performing 1 ' necessary rehabilittion work. 1. Remove the existing concrete side walk and dispose of off site. 2. Remove existing base material and set aside for reuse. 3. Scarify the upper 12 inches of existing site soils and recompact to 90 percent of maximum density at moisture contents 4 percent wet of optimum moisture. Every attempt should be made to create a uniform subgrade such that the replacement of base is to a uniform thickness. 4. Replace bas.: material to a minimum thickness of 6 inches and compsct to 95 percent of maximum density at rear optimum moisture contents. ' S. Tests And lnsnoctior,s: An adequate number of field density tests should be taken during compaction operations to ensure desired perccntafies of re!mive compaction are achieved. ,�0 2359 I Pale 5 RECOMMENDATIONS- Continued i Test and Inspections-Cont. r : Maximum density to control rnmpactionoperations is to be determined in accordance ' with ASTM b 1557-70 test procedures modified to use 3 instead of 5 equal soil layers. Inspections of cut off wall depths, as described in the following paragraph 7, should* E be made to confirm adequate embedment. 6. Replace the walk slab with a new slab a minimum of 14 inches thick, reinforced with r 6 x 6 - 6/6 wire mesh or #3 bars, 1£ inchs center to center. 7. Comments- i Plans should be reviewed to confirm depth of foundations or cut off wails, if any, enclosing planters. i ' Where plans indicate such systems are embedded less than 24 inches into subgrade 1 i soils, it will he necessary to construct cut off wall adjacent to planters to adepth of ;. 24 inches to retard lateral migration of water from landscape irrigation. r i A structural engineer should be retained to review the minimum slab thickness and ' reinforcing presented in the above paragraph 6. Upon such review, an increase in t concrete thickness and/or reinforcing requirements as appropriate should bo II?CllidCd � in design. � }�( rl . r it � r • _ 1I 2359 I',trc ( 4 1.11",> IN(: RECONI.%IlilVl)ATIONS - Contied NOTE The recommeriations contained in the report reflect our best estimate of soil conditions ' based upon information obtained from the limited number of test borings performed.
