oa Civil Engineering = Siviele Ingenieurswese - Innovative solution for fracturing rockmass
Extracted from text ... SLAKING AND DISINTEGRATION in Karoo Mudstones is a well known, extensively documented geotechnical problem, especially when ongoing disintegration in rock cuttings results in undermining of more resilient overlying sandstone, with concomitant crashing of these onto the roadway. Recent investigations into continuous ravelling and loose rock falling onto National Route N2 in the Kei Cuttings of the Eastern Cape have resulted in innovative and cost-effective methods of stabilising rockmass exposures susceptible to this mode of failure. DISINTIGRATION IN MUDROCK One of the major engineering problems associated with the rapid weathering of mudrock surface on exposure is when disintegrating or slaking rock in ..
