Aggregate Impact Value (AIV) apparatus conforming to IS 2386 Part IV and IS 5640 — used by road contractors, PWD labs, and civil engineering institutions across Northeast India for aggregate quality testing. In stock at Multi Trade Combines, AT Road, Guwahati.
The Aggregate Impact Value (AIV) apparatus is a standard civil engineering testing instrument used to measure how well road aggregates resist sudden impact loading — a property directly related to the long-term performance of road surfaces, particularly on high-traffic National Highways and State Highways across Northeast India. The test is specified in IS 2386 Part IV and referenced in IS 5640 (highway aggregate standards), making it a mandatory quality control check for PWD contractors, NHIDCL projects, and road construction agencies operating in Assam, Meghalaya, Arunachal Pradesh and throughout the Northeast.
The apparatus consists of a cylindrical steel cup (sample container), a guided hammer of standardised mass, a fixed drop height, and a base anvil. Aggregate is filled in the cup and subjected to 15 hammer blows of standardised energy. The broken sample is sieved, and the percentage of fines passing a 2.36 mm sieve is the AIV number — lower is better. Aggregates with AIV below 10 are classified as exceptionally strong; values above 35 are unsuitable for wearing courses on surfaced roads. This straightforward test gives site labs and consultants rapid feedback on stone quarry output quality, allowing quarry selection and source approval decisions to be made without costly long-lead laboratory tests.
Civil lab technicians in Guwahati use the AIV apparatus alongside the Los Angeles Abrasion Test, Flakiness and Elongation Index, and Aggregate Crushing Value tests to give a complete picture of aggregate quality for the BIS/IRC specifications that govern road projects in the Northeast. Multi Trade Combines supplies the full range of civil lab equipment — AIV apparatus, cube moulds, compression testing machines, sieve sets, Marshall apparatus, CBR testing machines, and more — from our AT Road, Guwahati counter, with shipping across all eight northeastern states.

PWD Assam and NHIDCL-contracted road construction labs, civil engineering colleges and polytechnics with materials testing facilities, private civil contractors with on-site quality control, and aggregate quarry operators doing source qualification testing all use the AIV apparatus regularly. The Northeast's road construction boom under the Bharatmala and NHIDCL programmes has substantially increased demand for civil lab testing equipment in Guwahati over the past decade, as consultants and contractors must document aggregate quality compliance for project handover.
Pairs well with: IS Sieve Set, Aggregate Crushing Value apparatus, Los Angeles Abrasion Test machine, compression testing machine, and cube moulds — all available at Multi Trade Combines.
The AIV test determines the resistance of road aggregates to sudden impact (shock load), which simulates traffic loading on road surfaces. Aggregate with a low AIV (high impact resistance) is specified for wearing courses on heavily trafficked roads. IS 2386 Part IV prescribes the test method, and IS 5640 covers highway construction aggregate requirements. Civil contractors and PWD labs across Assam use this test routinely for material approval.
Yes. The Aggregate Impact Value apparatus supplied by Multi Trade Combines conforms to IS 2386 Part IV specifications — cup diameter, hammer mass, drop height, and anvil design per the standard.
