During heavy downpour, the soil beneath the driveway keeps chipping away. Please can someone advise a cheaper solution to this?

    Hi Nigel,

    Welcome to theconstructor.org . I understand your requirements.

    • Scoring is defined as a process due to which the soil or rock particles around the abutments periphery or periphery of the pier of the highway bridges spanning are gets corroded and removed up to a certain depth which is called scour depth. Scoring can easily be observed.
    • Scoring is not the term related to pavement and concrete.
    • To avoid the removal of subgrade below the concrete for bituminous pavement is shoulders must be provided. Also, the embankment must be provided with proper slope and suitable method of stiffening and compacting should be adopted.

    The most economical method of compacting is uses of bamboos and root fibres in the soil which makes it steep compact and highly tensile resistant.
