Construction of Maine’s First Turnpike


Consulting engineers for the first-ever turnpike turned to the Asphalt Institute and E.M. Howard, District Engineer in Boston, to garner the expertise on materials and sound engineering practices to construct the turnpike in Maine completely with asphalt.

Canal Water Loss Prevention Research


The Bureau of Reclamation asked the institute to research using asphalt liners to prevent water loss in canals. This research resulted in liner and seepage containers as well as reservoir linings and dam facings on the Pacific Coast.

New Divisions Formed


The Asphalt Institute Board of Directors consolidated the field engineers and districts under five divisions – the Atlantic and Gulf Coast states; the Ohio Valley; the Great Lakes and Midwest; the Southwest; and the Pacific Coast, Alaska and Hawaii.

Twelve New Members


Fourteen non-member companies were invited to a meeting in Kansas and twelve joined the institute.

New President Named


With Asphalt Institute membership consisting of 22 producers, Herbert Spencer, Standard Oil Company of New Jersey, was named President of the Institute. Membership rose 56 percent and several district offices were opened. He served in this role to 1947.

Heavy-duty Pavements


The Corp of Engineers asked the Asphalt Institute to provide expertise about rock and asphalt for heavy-duty pavements. O.J. Porter proposed the design that would allow the new B-29 bomber to properly operate.

Washington National Airport


Through W.R. Macatee’s promotional efforts, the Washington National Airport was newly constructed with one million square yards of asphalt.

Stabilization Projects Begin


The Corps of Engineers asked the Asphalt Institute to develop an asphalt mix with local sand and filler to stabilize large voids in the Galveston, Texas jetty and make it permeable. This process resulted in numerous stabilization projects with asphalt including a sea wall in Holland.
