	When deemed necessary coarse aggregate intended for use in portland cement concrete may also be subjected to additional tests including: magnesium sulfate soundness, potential alkali reactivity of carbonate rocks, rapid freeze-thaw and alkali-silica reaction in concrete.

	Coarse aggregate tests consist of sieve analysis, specific gravity, absorption, rodded unit weight, Los Angeles abrasion, deleterious content, micro deval, and soundness (water-alcohol and sodium sulfate). The minimum time required for completion of tests is 16 working days from the date received unless T161 testing is required, then a minimum of 5 months should be allowed. Test results and calculations shall be recorded through AWP.		Coarse aggregate tests consist of sieve analysis, specific gravity, absorption, rodded unit weight, Los Angeles abrasion, deleterious content, micro deval, and soundness (water-alcohol and sodium sulfate). The minimum time required for completion of tests is 16 working days from the date received unless T161 testing is required, then a minimum of 4 months should be allowed.

			Conditional approval for use of PCCP and PCCM may be granted based off the results of the above listed tests, however, care must be taken when allowing conditional approval under these conditions as the results of durability factor and reactivity may result in the conditional approval being revoked and the material not being accepted for PCCP or PCCM use.

			Both PCCP and PCCM will be evaluated for reactivity under MoDOT Test Method TM-93. If AASHTO T161 Resistance of Concrete to Rapid Freezing and Thawing is required, testing may take up to 4 months to complete from date received. If ASTM C 1105 Standard Test Method for Length Change of Concrete Due to Alkali-Carbonate Rock Reaction is required, testing may take up to 15 months to complete from the date received.

			Test results and calculations shall be recorded through AWP.

	Fine aggregate tests consist of sieve analysis; specific gravity; absorption, rodded unit weight; other deleterious substances, clay lumps and shale, and lightweight particle content when specified; and mortar strength test.

			====1005.4.2.14 Alkali-Carbonate Reaction in Concrete====
			The State of Missouri has aggregate formations that are prone to alkali carbonate reactivity (ACR). This reaction is caused when the alkali contained in the Portland cement reacts with the aggregate, chemically changing the aggregate to an expansive material. Concrete that uses aggregate prone to ACR will experience significant map cracking caused by the aggregate expanding inside the concrete. Currently, there is no way to mitigate this reaction. The only way to prevent this reaction from occurring in concrete (masonry or pavement) is to avoid using aggregates prone to ACR. MoDOT has two ACR screening protocols for evaluating coarse aggregate. One protocol is for handling new quarries or new ledge combinations coming online. The second protocol is for handling existing quarries that have previously been sampled and tested for Source Approval. See EPG 106.3 for MoDOT Test Method TM-93 – Alkali Carbonate Reactivity Screening Protocol.
