Economy in the use of bitumen for road construction and maintenance is considered essential in view of the cost element and the knowledge that such costs are rising. Reference is made to minimum bitumen requirements to comply with road specifications issued by the Indian Roads Congress - based on quality, gradation and quantity of aggregate materials. A brief account is presented of economy measures which it is suggested could be adopted in bituminous construction, allied to the use of the correct choice of bitumen, delivered in bulk (at a saving of rs200-250 per tonne) rather than in packed drums (at about rs1200 per tonne), and by the correct choice of aggregate materials. Some economic bituminous road specifications are described and recommendations made for their use related to mechanisation and quality control. (TRRL)
