4. Contoh Perhitungan Uji Marshall:

Berat Jenis Bulk Agregat (hasil pengujian) = 2,576 gr/cm2

Berat Jenis Aspal (hail pengujian) = 1,056 gr/cm2

Angka Kalibrasi (ditetapkan) = 7,743

P (Kadar aspal tengah) = 7%

Berat Agregat F1 + F2 + F3 = 1200 gr

Untuk Kadar Aspal P-1, Sampel 1

Tinggi Sampel (t) = 5,67 cm

Aspal Terhadap Agregat (a) = P-1

= 7%-1

= 6%

Aspal Terhadap Campuran (b) =1200 x6%

1200+(1200 x 6% )x100

= 5,66%

Berat Jenuh Benda Uji (c) = 1102 gr

Berat Kering Benda Uji (d) = 1108 gr

Berat dalam Air Benda Uji (e) = 621 gr

Berat Isi Benda Uji (f) = d-e

= 1108 – 621

= 487 ml

Berat Isi Benda Uji (g) = cf

= 1102gr487ml

= 2,26 gr/ml

Pembacaan Dial (o) = 132 kg

Stabilitas (p) = o x angka kalibrasi
