backfill placed. Density testing of pipe backfill will extend from an elevation corresponding to the invert of the pipe to the subgrade elevation. • In-place density tests within the stabilized subgrade and base course layers at a frequency of 1 test for each 200 lineal feet of roadway. • Sampling, slump testing, molding, transporting, curing, and laboratory testing to determine the compressive strength of concrete used for headwall construction. Laboratory Testing • Perform laboratory moisture -density relationship tests (AASHTO T480 and AASHTO T-99), sieve analysis, organic content tests, and Atterberg limits determination on the existing embankment soils and/or fill soils. • Limerock Bearing Ratio (LBR) tests for stabilized subgrade and base course at a frequency of 1 test for about each 1000 lineal feet of roadway. Asphalt Paving& Testing • Asphalt paving observations by a Level I Asphalt Technician. Technician will verify thickness, temperature, and mix design tickets during asphalt placement. • Coring of the asphalt at ten (10) locations (a frequency of one (1) core about every 250 lineal feet) for subsequent laboratory testing and to verify asphalt and base course thicknesses. • Laboratory testing of the asphalt cores to include determination of specific gravity (density) for each core and extraction/gradation testing on select cores (5). Engineering & Reporting • Engineering oversight during the construction to coordinate the aforementioned test program, make site visits, and attend progress meetings. • Submittal of brief engineering reports documenting our findings and test results. All work shall also comply with the current Florida Minimum Technical Standards.
