Even with the widest roadbed now in use, based on this information, it would be necessary, in order to get good clearance from the track, to build out the shoulder to properly support signs located on embankments.

Clearance required for snow plow wings, roadbed spreaders and weed destroyers which are used on practically all railroads has been investigated and we believe that sufficient clearance has been provided for this equipment.

Your Committee, therefore, has recommended the distances given on the table submitted with this report, appreciating the fact that widening of the roadbed on fills will be necessary, and further, that this is the practice in vogue on railroads at the present time where signs are located at a sufficient distance from the track to require it.

Appendix B

SUBSTITUTES FOR WOOD CROSSING PLANKS

F. D. BATCHELLOR, Chairman; G. N. EDMONDSON, Vice-Chairman; ANTON

ANDERSON, C. H. N. CONNELL, Arthur Daniels,

R. A. Harry, Sub-Committee. In 1913 this Committee submitted a report on "Track Construction and Flangeways at Paved Street Crossings and in Paved Streets.” That report applied more particularly to crossings constructed of the same material as the adjoining street. The present report is more general and includes all kinds of crossings. It is a preliminary report, but is presented as information at this time, because of general interest in the subject.

In recent years the high price of wood crossing plank has resulted in the introduction of a number of substitutes, of which seventeen, if paving blocks are included, have come to the attention of this Committee. These may be grouped in five classes in accordance with the material of their construction. So classified, these substitutes are listed below. The figures under the group headings indicate the number of crossings of that group included in this report. Concrete

(a) Solid concrete. 21

(b) Precast slab.

(c) Concrete plank.
Bituminous Ma- (a) Tarvia.
terial

(b)) Headley Good Roads Oil.
57

(c) Emulsified Asphalt.
(d) Kentucky Rock Asphalt.
(e) Sheet Asphalt.

(f) Paving Pitch.
Steel or Iron (a) Innus Armco Iron Highway Crossing.
3

(b) Jennings Steel Crossing.

(c) Railroad Rails.
Paving Blocks (a) Granite.
8

(b) Brick.

(c) Wood. Ballast Material (a) Gravel. 1

(b) Disintegrated Granite. The information presented on the following pages covers 95 individual crossings, many of which were visited by members of this Committee. Data in regard to others was obtained from railroad users and from the manufacturers. For the most part, these crossings have been in use but a short time, and definite conclusions as to maintenance cost and serviceability tannot be reached. A number of roads, however, in addition to those reported on, are giving consideration to the adoption of one or the other of the substitutes. Plans or photographs of each type are included in the report.
