The aggregate samples were removed from the base layer with the aid of basic tools such as small shovels and hand-held pick-axes to dig down to the bottom of the base-course aggregate layer. It should be noted that the authors visually inspected the base course layers during sampling and looked for evidence of contamination, infiltration, or pumping of fine materials from subgrade soils. Aggregate base course: An engineered material tested for compaction, and graduation. Used under foundation and asphalt. Screened Fill: A fill dirt with the rocks greater than 1 inch screened off. Use for general dirt needs. Top Soil: Tucson soil screened leaving a light semi-sandy loam. Fill Dirt: Dirt right out of the ground. May have some

ANALYSIS OF USING RECLAIMED ASPHALT PAVEMENT (RAP) AS A

One aggregate base course sample did not meet CDOT criteria because the liquid limit (LL) and plasticity index (PI) were out of specification; testing of this sample was discontinued. Overall, the resilient modulus (M R) testing was reduced because of funding issues. Poisson's ratio testing was suspended because quotes obtained were greater than the total cost of the study's testing budget. 4

Granular Base Course: A mixture of soil particles ranging in size from coarse to fine. Processing involve crushing oversized particles and screening where it is necessary to secure the desired grading. The requirements of a satisfactory soil aggregate surface are: Stability; Resistance to abrasion; Resistance to penetration of water ; Capillary properties to replace moisture lost by surface

However, it is less applied in the base course. The feasibility of the application of steel slag in the road base was examined and the optimal replacement content of aggregate was determined. Different contents of steel slag (30%, 50%, and 70% by volume) were blended into the concrete. The mechanical and durability performance of the mixture were tested. The microstructure and elements

The aggregate base course shall be constructed to the width and section shown in the DRAWINGS. If the required compacted depth of base course exceeds six (6) inches, the base shall be constructed in two (2) or more layers of approximate equal thickness. The maximum compacted thickness of any one (1) layer shall not exceed six (6) inches. B. Each layer shall be constructed as far in advance of

Aggregate. Various tests, including quality, freeze-thaw, and alkali-silica reactivity (ASR) are performed on aggregates used for road and bridge construction in Illinois. These tests quantify the physical characteristics of each aggregate product from each source. Development and evaluation of all statewide aggregate related policies, procedures and specifications are continually modified to
