NCHRP 04-34 [Completed]

Application of LADAR in the Analysis of Aggregate Characteristics

  Project Data
Funds: $500,000
Research Agency: Virginia Tech Transportation Institute
Principal Investigator: Linbing Wang
Effective Date: 6/20/2006
Completion Date: 3/31/2012

The objective of this project was to develop and evaluate a LADAR system capable of precise and accurate measurement of the aggregate characteristics of shape, volume, angularity, surface texture, specific surface area, and volumetric gradation. The LADAR system would be applicable to aggregate in each of three size categories, coarse (2 in. to No. 4), fine (No. 4 to No. 200), and microfine (P200), and would be suitable for routine use in research, central, and field laboratories for PCC and HMA mixture design and quality assurance.

The project final report, including Appendixes B, C, and D, is available as NCHRP Report 724, Application of LADAR in the Analysis of Aggregate Characteristics. Appendixes A and E through J are available to download at http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP04-34_NR724AppendixesAE-J.pdf.
