ASPHALT AND RELATED BITUMENS 1187


 Increased construction of lighter-type asphaltic highways is indicated I~y
greater sales of cut-back asphalts than in 1940. Total sales of rapid-curing
and medium-curing cut-backs increased 10 percent in quantity—from 1,722,475
to 1,903,132 tons. The greatest gains were in the East Coast district, the
Oklahoma-Kansas-Missouri district, the Louisiana-Arkansas district, Texas,
and the Rocky Mountain district Against these gains were a sharp dechne in
the IndianaIllinois-Kentucky-etc. district and smaller declines in California
and the Appalachian district. Most of the gain in sales of cut-back asphalts
was in the medium-curing type, and the greatest increases in that type were
in the East Coast and Oklahoma-Kansas-Missouri districts.

* Petroleum refineries sold 85,570 short tons (20,162,003 gallons) 01 emulsified
asphalts and fluxes valued at $887,202 in 1940 and 129,006 tons (30,396,265
gallons) valued at $1,576,840 in 1941; in addition, 45,924,626 gallons valued
at $3,385,468 in 1940 and 76,830,549 gallons valued .at $6,919,102 in 1941
were sold by major industrial companies that purchased asphalt from petroleum
refineries. Accordingly, total known sales of emulsified asphalts and fluxes
increased 62 percent in quantity—from 66,086,629 to 107,226,814 gallons—and
99 percent in value—from $4,272,670 to $8,495,942.
 Roofing manufacture made the second-largest demand for asphalt, absorbing
25 percent of the sales to domestic consumers in 1940 and 27 percent in 1941.
Although shipments of prepared roofing arid asphalt siding reported to the
Bureau of the Census increased 29 percent—from 34,222,039 squares in
1940 to 44,112,699 squares in 1941—domestic sales of roofing asphalt
and roofing flux combined increased 37 percent—from 1,218,695 to 1,671,696
tons. Some roofing and asphalt siding, however, is made by petroleum refiners
who do not report their consumption of asphalt for roofing manufacture among
their sales. The increase in sales of roofing asphalt and flux was general.
The principal gain was in the northeastern quarter of the United States—notably
in the East Coast and Indiana-Illinois-Kentucky-etc. districts. Substantial
gains occurred also in the Oklahoma-
