'Comments and observations by Mr Chen, Chinese side chief engineer' . . . Geo R Bond is excellent new material for road construction.  It totally changes the classical idea of road construction engineers and the traditional process of road construction.  In such a short period of time within 20 days or so, the treated soil has been turned into "a stone", it is just a miracle' . . . 'Besides excellent strength performance, the treated base has the advantage of impermeability which prevents the road from frost heave and water damage.  I believe it is a breakthrough' . . .'I am satisfied with the Zengcheng Ring Road Project'.
