Cohesive strength test- unusal application

Cohesive strength test- unusal application

Cohesive strength test- unusal application

(OP)
Penetrometer test for surface hardness is not enough for this complicated setting! What tests are used for cohesive strength/ shearing resistance for soils, concrete, or asphalt? Test for abrasion-resistance? What are the standards to resist abrasive wear in waterways?
My very unusual application:
Coal tar was lost to river during 100 years of gas works operations & covers over 5 acres of river bottom. Consistency is similar to a mix of perhaps 1:1 to 3:1 of roofing cement:sand/gravel. It is weathered with a hardened skin but tests show its high in BTEX, napthalenes, & PAHs (>20,000 ppm). Evaluators claim its hardened surface limits exposure to fish, people, & biota. I'm looking for tests & standards (prefer in-situ) to demonstrate materials' integrity (or failure) to withstand nature's forces: raging river carrying trees, foot traffic (wading fisherman), small boats grounding on it, etc. Be inventive & think outside the box.

RE: Cohesive strength test- unusal application

Coal tar is considered carcinogen. It's harmfull to the human and polutant to the nature. Do you try to use the forum to cover the disaster of river poluting?
