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.
