I7►e antlysis was based on atimated <br /> C�R and rosilient modulus(M,) vdues estimated from the raulu ofour field investiguion u <br /> weU as previous experiana� wl�h si milar soil types, u�d on the uwmption that the subgrade <br /> f�the propo�d parking and driveways would be prepared in wnformance with the <br /> recommendation is the preceding section. <br /> We have not been provided with any traftic frequency snd axle loads for the daign of <br /> the pulting lot.Qavement. The design ESALs(Equivalent Single Axle Loads)used ia the <br /> unlysis are atimated and is based on the inference that the proposed psvement will be <br /> utiliud primuily by light Vaffic. <br /> We rxommend that the pavemeat sectioos be placcd oa a ProP�Y P�P�� <br /> approved subgrade consisting of compaaed sttuctural fill. We recommand proofroUing t6e <br /> pavemmt wbgrade by a loaded dump wck so that soR or yielding areas can be repsired prior <br /> to the placemwt of the pavemem ucrioa <br /> We have developcd a pavement section baud on the subsurface soil conditions <br /> mwumered in Tat Pit#1. Based on our acpe�ience with soils of simitar gradatioa and <br /> consisteary,and the use ofgeotcxtile fabric for subgrade strengtheniag, a CBR value of 9 has <br /> ban assumed for t6e flexible pavement design. This CBR value corresponds to a resilimt <br /> modulus(M�valuc of 7,200 psi. <br /> Paveme�u daign prceedura are based on the sa�enngth propatia of the subgrade and <br /> pavemem materials,atong with the daign uaffic coaditions. Coatidering that t6e vaffic mix <br /> will generally include pauenger cars,vans, light duty tcucks,aad 18,00016. Singie axle heavy <br /> delivery uucks,light duty flexible paveme�secrions are recommended for the general <br /> parlong areas,�nd rigid sectioas aze recommended for the loading/unlosding areas whae <br /> heavy traffic is anticipated. <br /> A proper drainage system is essentisl for tlu adequate pafocmance of pavemeat. Tha . <br /> drainage system should be designed for the rapid removal of water&ow the pavement wrface <br /> and from the pavemrnt sectioa below. <br /> The following IigM duty flexible pavement section should be used for the general <br /> parking azeas, and rigid pavement sections should be used for the loading/unloading arcas and <br /> drive through. <br /> 8 <br />
