i Durability Of Concrete. .-
Il Concrete In point of durability is an
Il element OF weakness for the reason
Il that IL does not unite with the surface
4 and provides a line OF separation be-
tween the foundation and surface, the
4 tendency OF which is 10 cause the
Il pavement to slip or roll on the foun
! dation under the rolling effect Of
traffic.
i h is not uncommon TO see pave
ments which have rolled into waves
4 or pillows, and upon examination to-
4 find that the surface has slipped on
j the concrete TO such an extent that
4 the upper surface Of the concrete and
1 the lower surface Of the pavement have
/ become as polished as glass.
i The bitumfnons foundation Of the
4 bitu1ithic pavement provides a rough
surface OF the same character as the
wearing surface. so that Under pres

\ The weakness is In the surface and

i base being united and the surface
pressed into the same, the entire
thickness Of the sufface will wear
evenly. and after worn to the base il

] do not want to be misunderstood;
we do not decline to lay bitulithicI
pavement on d concrete base II It Isl
so desired, but our experience Is that
rock base, provided the same has a.
Il good sub-foundation and the rock Il.
i properly rolled.
The first bitulfthic pavement was
laid In 1901. a total yardage of IL, zoe
square yards and steady increase
has been shown up to 1913.
i During tho year 1882 5.Se7. 638
/ square yards were laid In over 250'
cities, and the yardage for 1913 ex.
ceeds that figure.
i The following qualities are those In
4 which bitulithic pavement excel
tCheapness. durability, easiness Of.
| cleaning, light resistance to traffic.
4 non-slippe ease Of maintenance.
lfavofabIeness TO travel, sanitariness.
i Ernest McEoliouch, formerly con.
suIting engineer for the Merchants
Association OF San Francisco. has the
following to say regarding bituiithic
i pavement.
The writer wishes to 60 upon rec
/ ord as saying that with honest work
manship and honest materials the Bit
i ulithic pavement in my opinion has
q larger percentage of desirable oual
tiles than any material am acquaint.
ed with. 1t approaches very nearly.
the ideal pavement.
Another strong argument in favor
iof bitulithic pavement 10 the persist
ance OF various competitors In trying
to initiate as closely as possible the.

rem brothers, patents.
i None, however, have been able to
produce pavement that can com.
lpare with bitu1ithic when it comes to
! the question or durability and other
desirable qualities.

Many contractors have, found 1t

Great stress is put upon the fact

j This can be easily determined by
