Concrete inFocus - Fall 2017 - OC4

trends with fleets that include at least one
mixer truck with a conveyor system attached,
these data suggest that this frequency is about
one in 14 companies.

Chassis Configurations
Over the last several decades many variations in axle configuration have been developed in response to varying state weight laws.
According to the 2017 Fleet Survey, three-axle
and four-axle booster or pusher configurations
are most common. This accounts for about
60 percent of the operating mixer trucks. In
order to meet federal bridge weight restrictions and increase load carrying capacity,
more ready mixed concrete trucks are using
four or more axles. In the four-axle category,
tail axles outnumber pushers by more than
7-to-1. However, the data may be biased by the
geographical distribution of responses and the
pertinent state and local weight restrictions.

Fleet Performance
The survey represents ready mixed concrete
trucks that traveled more than 273 million
miles, equal to almost 11,000 trips around
the equator. The average annual mileage on
a ready mixed concrete truck last year was
16,419 miles. This total is up over last year,
but considerably lower than the high number
recorded in the last 10 years of 18,896 (2006
survey). Another interesting benchmarking
data point is miles per cubic yard. This is
calculated by dividing average truck miles
by average total cubic yards delivered per
truck. Nationally, that number this year is
3.24 miles/cubic yard (3.28 in 2015). Miles
per cubic yard can give a company an idea of
how well its operation is able to acquire jobs
close to the production facility. Naturally,
large urban areas will have an advantage over
more rural areas. The average haul distance
a mixer truck must travel will vary depending on location, type of construction and
commitment to customers. The average oneway haul distance for the 74 companies that
reported data was 15.86 miles (the highest
in the survey's history).
For this survey the average load-size was
8.19 cubic yards and the average full load
was 9.80 cubic yards. Both figures are about
the same as last year's survey. Important to a
ready mixed concrete producer is the "loadsize coefficient" which can be calculated by
dividing average load-size by typical full-loadsize and multiplying times 100 to convert to

a percentage. In general, the higher the load
size coefficient, the lower the cost of trucking
per cubic yard. Of the 75 companies reporting
both numbers, the calculated average load-size
coefficient was 84%, with a high of 98% and
a low of 62%.

Fuel Consumption
One of the major costs in operating a
ready mixed concrete fleet is fuel consumption. In the last few years our industry has
seen unprecedented price swings for diesel
and gasoline. Fortunately, it appears that
