NICET Highway Construction Materials Testing

Question 1

Which NICET certification covers technicians who test soils, aggregates, and concrete on highway construction projects?

Accepted Answer

Highway Construction Materials Testing (HCMT)

Answer

NICET's Highway Construction Materials Testing (HCMT) certification covers technicians who perform quality assurance testing of materials used on highway projects.

Question 2

What test is used to determine the moisture-density relationship of compacted soil?

Accepted Answer

Proctor Compaction Test

Answer

The Proctor Compaction Test (AASHTO T 99 or T 180) determines the relationship between moisture content and dry density for soil compaction control.

Question 3

What does a nuclear density gauge measure on a highway construction site?

Accepted Answer

In-place density and moisture content of soils and base materials

Answer

A nuclear density gauge uses gamma radiation and neutron emission to measure the in-place density and moisture content of compacted soils and base materials.

Question 4

Which AASHTO standard governs the sieve analysis of fine and coarse aggregates?

Accepted Answer

AASHTO T 27

Answer

AASHTO T 27 is the standard method for sieve analysis of fine and coarse aggregates used in highway construction materials testing.

Question 5

What is the purpose of the Los Angeles Abrasion Test?

Accepted Answer

Determine resistance of coarse aggregate to degradation by abrasion and impact

Answer

The LA Abrasion Test (AASHTO T 96) measures the percentage of wear in coarse aggregate subjected to abrasion and impact in a rotating steel drum.
