life of the road. I f th e cem enting qual
¡tv is not good, the dust will d ry out
and blow aw ay. Thus, in the la tte r in ­
stance, the road would Boon be found
in “ broken d o w n " condition.
B asalt, which ia plen tifu l in most
section» of th e P acific N orthw est, usn
ally is a fa irly good road stone. B ut net
always, ns herein lies a stum bling block
for many builders o f roads. In the
early tim es of creation, b asalt, in a
lava like form , oozed through fissures
in the e a r th 's surface, and spread ont,
in la te r ages, «doling. P erhaps the big
gest “ B asaltic O v erflo w ’’ in the world
exists in th e P acific N orthw est.
It
reaches from the C anadian boundarv to
C alifornia, ami eastw ard to the foot
hills of th e Koekies. A lthough preaerv
ing.j* general sim ilarity of ap|H‘aranee,
tho q uality o f L a-alt w ith reference to
to rsadm aking varies. The only sure
way to determ ine is to make a earefnl
anil scientific te sts; and if th e basalt
is found to be defewtive, the roadm aker
must tak e th is iuto consideration, or a
state or county Will, a few years later,
he found to have expended whole for
tunes in th e building r f p ractically
worthless roads.
C ivil Engineer, Too
The above is cited only as an ex­
ample of the m any problems which arise
in roadm nking, but whieh exist to a
g reater or leas e x te n t in practically
cv rry type of road m aterial used. Even
when well inform ed, au d with th e best
nf testin g m achinery and laboratory fa
eilities a t hand, th e good ro a d s’ en
gineer often runs am uck of new and
puzzling problems.
Sandstone usually is not very good,
thongh some of it is nil right. B asalt
usually is good. So is diorite, diabuse,
dolomite, nnd g ran ite, though, for rea
sons above indicated, it is unsafe to
say th a t any rock is good or bad till
it has been su b jected to tests for ce
ment value, hardness, toughness, ab
sorption, and so on.
W hile th e in terest of the highw ay en
gineer in .roadm aking m aterials is a l­
ways keen, his knowledge lim ited to
th is field would not m ake him a high
w ay engineer by any means. He must
be a civil engineer—m ust understand

how ever, the statew ide in terest in
good roads led to the estab lish in g of
a good roads labo rato ry at th e college,
equipped w ith such m achinery and f a ­
cilities as are necew ary to tra in spe­

are in terested in oth er phases of en
gineering.
On the college enmpus, a roadway
has been reserved for an erp er.m en t
w ith some fifte e n d iffe re n t kinds of
road surface.
The roadw ay reaches
from th e dairy building On tho fro n t
campus, out east to the college farm ,
and will be surfaced wifh d ifferen t
