Abstract
Systems and methods are disclosed for designing and tracking construction material usage by estimating volumetric properties for one or more mix designs; determining an optimum mix based on laboratory data; and field testing a sample of the optimum mix; and tracking and managing construction material usage based on the optimum mix.
Claims12
A method for designing and tracking construction material usage, comprising:
- estimating volumetric properties for one or more mix designs;
- determining an optimum mix of raw materials based on laboratory data;
- and
- field testing a sample of the optimum mix and compensating for variability in processed raw materials;
- and
- tracking and managing construction material usage based on the optimum mix.
3 more elements
A system, comprising:
- a gyratory compactor;
- a computer coupled to the gyratory compactor, the computer having computer readable code to estimate volumetric properties for one or more mix designs;
- run one or more tests on the mix design using the gyratory compactor;
- digitally collect data for each gyration from the gyratory compactor;
- and select an optimum mix based on the gyration data;
- and
- an asphalt content tester coupled to the computer to provide ignition data to test the mix;
- and
- computer code to track, compensate for variability in process raw materials and manage construction material usage based on the optimum mix.
