Two parking lots, one made of quartzite and the other made of natural aggregate, were compared using the Marshall method mix design test, skid resistance tests, and economic studies. It was found that the pavement with quartzite uses 13.3% less asphalt, gives a higher mean skid resistance, and saves 0.13 dollars per square yard per year during the life span of the pavement assumed in this study. It was determined that quartzite pavement is preferable to pavement with natural aggregate. The flexible pavement structure in a parking lot must have enough stability to meet the load exerted from parked cars as well as the rolling action of traffic. The surface of parking pavement does not receive the same degree of compaction from the rolling action of traffic as it would under normal road usage. Therefore, the design surface, base course, and wearing course must be adequate to distribute the standing and slow-moving loads over a sufficient area of sub-grade in order to prevent the surface from deforming. The relative value of using quartzite and natural aggregate is considered here. The use of quartzite and natural aggregate as construction materials for roads goes back several hundred years. The natural aggregate (gravel) was used then to make hard earth roads. At the present time quartzite and natural aggregate are used for the sub-base, the base, and the surface pavement. The surface pavement can be anything from a simple surface treatment (chip seal) to a full depth asphalt pavement.
