INTRODUCTION. 
The purpose of this paper is to supply reliable information on the 
subject of Portland cement concrete pavements for the use of high- 
way engineers and others interested in the improvement of public 
roads. It is realized, however, that the present state of knowledge 
concerning the best methods of constructing such pavements is by no 
means complete, and those who have charge of concrete-road con- 
struction should be careful to keep themselves informed regarding 
results obtained by others engaged in similar work and by laboratory 
experiments. 
The earliest concrete pavement in the United States of which there 
is reliable record was constructed at Belief ontaine, Ohio, during 1893 
and 1894. This pavement contains 4,400 square yards and w T as con- 
structed in squares similar to those employed in concrete sidewalk 
construction. The concrete was laid in two courses. This early ex- 
periment indicated many possibilities and no doubt has been respon- 
sible for some of the construction methods in use at present. Prior 
Note. — This bulletin contains reliable information on the construction of Portland 
cement concrete pavements for country roads. Practical instructions for highway engi- 
neers and all others interested in road making are given.
