CODE OF ORDINANCES OF THE CITY OF LITTLE ROCK,
ARKANSAS; ADDING SECTION 36 -18 TO SAID CODE OF
ORDINANCES; AND FOR OTHER PURPOSES.
NOW, THEREFORE, BE IT ORDAINED BY THE BOARD OF DIRECTORS
OF THE CITY OF LITTLE ROCK, ARKANSAS.
SECTION 1. Section 36 -12 (c), Thickness requirements for
flexible pavements, is hereby amended to read as follows:
(c) Thickness requirements for flexible pavements.
Thickness for all flexible pavements, classes 1 through 4, may be
determined by soil tests run by a reputable testing laboratory.
The tests shall include characteristics for identifying P. R. A.
soil groups and the Hveem Stabilometer resistance value. Soils
having an approximate Hveem Stabilometer resistance value of
twenty as determined above is the basis on which the following
standards are established. The standard pavement as outlined in
these specifications shall be defined as asphaltic concrete hot
mix wearing surface placed on a compacted crushed stone base course.
All types of flexible pavements including soil cement stabilization
with asphalt surfacing shall be permitted providing, in the opinion
of the city engineer, the plans and specifications and construction
will define and will result in a pavement of equal or greater
stability. The total thickness shall be determined by the methods
outlined in the specifications. ,

less than twenty. Should the Hveem Stabilometer resistance
values be less than twenty, the above standards shall not govern,
and the total pavement thickness shall be determined based on the
test results. Should the Hveem Stabilometer resistance value be
•
greater than twenty, the above standards shall be modified as
determined by the test results, but in no case shall the total
thickness of the standard flexible pavements be less than two in-
ches of asphaltic concrete surface and six inches of compacted
crushed stone base material. Asphalt treated crushed stone base
course may be substituted for the compacted crushed stone base
course at one to two substitution ratio with a minimum reduced
thickness of three inches, provided the Hveem Stabilometer resis-
tance value of the subgrade is greater than 35, and the alternate
construction will result in a pavement of equal or greater sta-
bility, in the opinion of the City Engineer. Asphalt treated
crushed stone base course construction shall comply with current
Arkansas State Highway Department Specifications Special Provision:
ASPHALT TREATED CRUSHED STONE BASE COURSE.
SECTION 2. Section 36 -18 shall read as follows:
Section 36 -18. VIOLATIONS -- PENALTY. Any person, firm or
corporation violating any of the provisions of this article shall,
upon conviction, be fined any sum not exceeding $200.00, and each
day the violation continues shall constitute and be a separate
